OIL-VAPORIZER.

.exact description of the invention, such as will enable others skilled in the art to whichV it appertains to .make and `use vthe same.

lMy invention lrelates to an improved vaporizer, ,the `object of the invention .being .tov provide an improved vaporizer that is vnot, dependent upon gas produced by ,itself to .fur-

gas or vapor for nish lthe vheat for generating but in which a .lighting or other purposes, lamp ,or other similar device Iis lprovide the necessary lheat without interferng with the ordinary light-giving .properties .or,other functions of the device.

Afurther objectis to provide an apparatus of this character which `will notcarbonize .to ,f such an extent as to destroy its/effectiveness j and in which no joints or other weak `parts are brought .into contact with the iiame.

A Afurther object is to provide an appara-1 tus in which the well-known needle-.valve is dispensed with and .in which the amount of flame or heat is always under the control of the operator and does -not depend yupon the apparatus, but is independent therefrom.

A further object is to provide a vaporizer of extremely simple and inexpensive construction, one that can be readily understood by any one of average intelligence and maintained in working order, and one that is strong and durable in use.

With these objects in view the invention consists in certain novel features of construc tion and combinations and arrangements of parts, as will be more fully hereinafter described, and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view in elevation, illustrating my improvements. Fig. 2 is a view in longitudinal section of the vaporizer. Fig. 3 is a view in section of the commingling or mixing chamber. Fig. 4 is a view of the valve, and Figs. 5 and 6 are views of a modified form of valve.

1 represents a lamp-casing, which may be of any form desired to receive an ordinary lamp 2, having the chimney 3. The casing 1 is preferably provided with a frame 4 at itsH top, made with inwardly-projecting lugs 5 to receive and support bent-over tongues 6 on a cross-bar 7, and a metal strap 8 is secured vSpecification of Letters Patent. Application filed August, 1905. Serial No. 272,891.

centrally@ bar 7 by@ Screw 9andl1cldsiii1 proper position my improved vaporizer-,tube 10. The ,tube 10 comprises l.a tube or 1rpipe bent upon itself and "extending 1down Lirito .chimney 3 the desiredjdistanceto,receive the heat .from the lamp without .interferingwith the flight-giving properties thereof.

One end of ,tube '10 -is connected by .ia ,pipe 11 with any desired reservoirior.othersource of .liquid-.hydrocarbon `Supply .and .has 00.0.1; 12 therein, which :latter is open .whilegenerating, and at alllothelr .times tightlyplosed'. The outlet Tend of lthe .vaporizer-,tube 1;() is ,provided with lmy improved valve 1 3 `directing the vapor .into an iair-.mixer .or .co-mmm gling-.chamber 14, which Ilatter ,has a .conical Vbottom y15 .and short removable 2cylinder thereon All upright :111g 16 -S ,Provided 1in .the :bottom to .receive a shortgrooyedstandard `1,7' on 1the lower endoifapipe 18, supporting the latter above the bottom and within the `chamber 14, yet providing ,ample yspace all around for the yentrance of l 1-own yinto the chamber to mix with the I.va or ,orjgas `discharged up into pipe :18, and t e gmixture isfconveyed by said pipe to Ethe points for use yeither .for .lighting or j other use.

Valve 1 3 which is locatedinsidathefconical `bottom ,15, yhas a turning plug or journal ;19, operated tby a long arm or lever 20, projecting lout of the `oomminglingfchamber i151. This plug or journal has a main opening through it to receive the vapor and is provided with smaller lateral ports to be moved into or out of alinement with a small port 21 in the valve-casing, and thereby govern the supply of vapor discharged, and consequently control the light-producing power of the mixture.

A modified form of valve is shown in Figs, 5 and 6, in which the casing is provided with vapor inlet and outlet openings and the plug with a peripheral roove extending considerably more than half way around the plug and in line with the vapor inlet and outlet openings in the casing. This groove gradually decreases in size from one end to the other, and when so turned that the peripheral groove is in communication with the vapor inlet and outlet openings the vapor will freely escape into the mixer, and by turning the plug the amount of vapor escaping may be regulated or cut off entirely.

In the downfeed-tube of vaporizer 10, receivin the oil from the source of supply, I provi e a wick or retarder 21a, comprising an IOO IIC

outer wire netting inclosing an asbestos or other fibrous packing which holds the oil and allows only the slow feed thereof, and consequently insures a steady vaporization of all oil passing through the vaporizer and results in a steady light at the burners and at the same time holds back foreign matter and im* purities of all kinds.

The operation is as follows: After the vap orizing-tube is heated by the lamp to the proper-temperature cock l2 is opened and the oil will saturate the netting-covered wick or re tarder and its impurities will be held there* by and the pure oil will pass down slowly from the wick or retarder and be vaporized,

yand as it passes around the lower bend of the tube and up the other side it will come in contact with the most intense heat and will ascend and escape from the valve 13 into mixing-chamber 14 in the form of a dry gas. Here it mixes with the air, as above explained, and passes to the burners.

A great many slight changes might be made in the general form and arrangement of the parts described without departing from my invention, land hence I do not restrict myself to the precise details set forth, but consider myself at liberty to make such changes and alterations as fairly fall Within posed over said illuminating-lamp, a port able vaporizer and means for conducting hydrocarbon thereto supported over the .burner of the lamp by said frame.

3. The combination of a portable frame, a portable illuminating-lamp supported thereby, said frame having a horizontal member above the lamp, and a vaporizer and means for conducting hydrocarbon thereto, supported over the lamp by the horizontal member of said frame.

4. The combination of a bent vaporizingtube, a lamp, a chimney into which the vaporizing-tube is projected, and an asbestos wire-netting-covered wick or retarder located in the oil-inlet side of said tube and retarding the feed and filtering impurities from the oil.

5. In a vaporizer, the combination with a lamp, of a vaporizing-tube projecting into the chimney of the latter and heated thereby, an air and vapor mixing chamber into which the vapor is discharged, and a valve, other than a needle-valve regulating the flow of vapor into the mixing-chamber.

6. In a vaporizer, the combination with a heater, of a vaporizer-tube heated thereby and independent of the fuel-supply of said heater, an air and gas mixing chamber, a tube for mixed air and gas in the chamber and providing an air-inlet all around the same, a plug-valve in said chamber regulating the escape of vapor or gas thereinto, and an operating arm or lever on said valve proj ecting out of the mixing-chamber.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
